There is a formula to height of masonry block wall, ratio of Block width dimension; i.e. 4" block, maximum 6' height. I've forgotten the formula and can't find note within my reference materials for maximum height of 6",8", 12". Can you help?
Have been setting spec for testing (psi and slump) concrete in sidewalks and/or curbing at mid-point per 9-yard truck load. Is this average ratio in the southeast?
Thanks
Vandals have been stealing the electronic sensors used on plumbing fixtures in our public restrooms. What else can these type sensors be used for that makes them worth stealing?
